Filed: 1973-07-19
Abstract: 1416242 Synchronous linear motors SIEMENS AG 19 July 1973 [15 Aug 1972] 34588/73 Heading H2A In a synchronous linear motor arrangement, a pair of inductors 3 are mounted adjacent a set of equally spaced non-laminated magnetizable bodies 2, and each inductor is formed by a first part comprising a laminated core 4 with a polyphase A.C. travelling wave type coil system (not shown) wound in core slots 5, together with a D.C. winding 6 on a solid yoke 7 on the back of core 4, and by second/third parts comprising laminated yoke bodies 8 energized by D.C. windings. In the arrangement shown, the bodies 8 are formed as extensions of yoke 4, but are isolated from yoke 4 by air gaps 9, and they are D.C. energized from winding 6 as a consequence of the yoke 7 extending at each end beyond the limits of core 4. In the arrangement of Fig. 2 (not shown), wherein only one inductor is used and the bodies 8 are non-laminated the yoke 7 does not extend beyond the core 4, and each body 8 is therefore required to be energized by a separate D.C. winding (10). In each case the bodies 2 are subjected to D.C. fields from the bodies 8 before they are affected by the travelling waves, and the efficiency of the system is said to benefit thereby.

Title: Process for determining cyanide concentrations in solution
IPC: G06F11/30
Filed: 1957-11-07
Abstract: 843,028. Electric tests. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT VORM ROESSLER. Nov. 7, 1957 [Nov. 9, 1956; April 26, 1957], No. 34742/57. Class 37. In a process for determining the concentration of cyanide ions in aqueous solution by measuring the potential between a reference electrode and a metal measuring electrode, an auxiliary current is caused to flow between the measuring and auxiliary electrodes the specification explains that the potential induction of the measuring electrode may lag considerably behind changes of cyanide concentration because of the failure of the Nernst double layer to vary with changes. It is stated that the auxiliary current makes the measuring electrode act as a dissolving anode thus causing the double layer to be placed constantly in equilibrium with the solution flowing past it. Fig 2. shows such an arrangement in which amplifier 6 and meter 7 indicate the potential between a calomel reference electrode 1 and a silver measuring electrode 2. The auxiliary electrode 3 is of gold and is connected to the measuring electrode by source 4 and variable resistor 5. The measuring electrode preferably consists of copper or any metal more noble than copper, or such a metal or copper alloyed with a less noble metal providing the less noble metal is ennobled by the more noble. Silver has been found to be particularly suitable for the measuring electrode which may be of pure silver or a more noble metal to which silver has been applied electrolytically, thermally, or mechanically. The auxiliary electrode consists of the same metals as those referred to above but the metals and alloy used for the auxiliary and measuring electrodes must form complex cyanides as the Nernst double layer with the cyanide ions in the solution to be measured this formation occurring on the measuring electrode and must be as noble as the noblest metal in the solution to be measured. The indications of the apparatus may be connected for pH. value by introducing a glass electrode into a differential circuit. The liquid under examination should flow past the measuring electrodes so that the diffusion factor plays no important part. The polarities of the measuring and auxiliary electrodes can be reversed at 30-60 minute intervals or they may be supplied with an alternating voltage to reduce hysteresis effects produced if the measuring electrode is charged with a layer of silver oxide or silver chloride.

Title: Improvements in forced-flow steam and other vapour generators
IPC: F22B37/14
Filed: 1936-12-18
Abstract: 489,168. Forced-flow steam boilers. BABCOCK & WILCOX, Ltd. Dec. 18, 1936, No. 34784. Convention date, Dec. 18, 1935. [Class 123 (ii)] In a forced-flow boiler having a number of parallel connected long small bore evaporating tubes 207 discharging into a separator 232, the steam is led from the separator through a superheater consisting of a number of parallel connected horizontal tubes 242 at different levels between upright headers 241, 243. At starting, all the tubes are filled with water and the burners lit, and when pressure steam discharges through a vent on the outlet pipe of the superheater, the vent is closed and a stop valve in the pipe is opened to supply steam to an auxiliary turbine driving the feed and fuel pumps. Water is supplied in excess of the quantity evaporated and the excess is continuously withdrawn from the separator. The evaporating tubes are fed from a collector 204 through resistors 205 and they are so arranged horizontally along and around the walls of the combustion chamber that thev are equally heated. The gases from the combustion chamber flow horizontally over the superheating tubes 242, feedheating tubes 202 and through an air heater 282 to the uptake. The superheating tubes are coiled to protect the walls of the gas passage.

Filed: 1975-08-21
Abstract: 1467220 Feeding animals ALFA-LAVAL AB 21 Aug 1975 [21 Aug 1974] 34832/75 Heading A1M Apparatus for feeding animals such as pigs reared in a group comprises a trough 3 divided by portions 12 into as many feed troughs as animals in the group and a feed container 1 provided with a distribution wheel 2 which supplies feed at a predetermined rate to the trough 3 throughout the feeding period such that each individual trough receives the same total amount of feed and the feeding period is pretimed to last as long as it takes the slowest eating animal of the group to consume this total amount of feed so that each animal of the group eats the same amount of food. Since animals eat faster at the beginning of a feeding period, the distribution wheel 2 is driven by a motor with a variable speed changer according to a selected program by means of a pre-set control unit (in accordance with known technique) such that the rate of supply is greater at the beginning than at the end of the feeding period and gradually decreased inbetween. The total amount of food given at a feeding period may be varied from day to day and preferably the animals are foddered more than three times per day. Each individual trough is provided with a valve 11 for the supply of water from a pipe 9 by means of an animal operated plate 10. The front of the trough 5 is stated to be shallower than normal for example plates 7 and 6 form angles of 150‹ and 135‹ respectively, with the trough bottom 8, so that the animal can empty the trough completely whilst standing at right angles to the trough.

Title: Improvements in apparatus for the reproduction of recorded sound
IPC: G11B11/00
Filed: 1921-12-29
Abstract: 195,715. Marks, E. C. R., (Soc. Industrielle des ProcÚdÚs W. A. Loth). Dec. 29, 1921. Ribbon-machines; ribbon rocords; optical records.-Apparatus for reproducing sound from a photographic film record of which one portion of the surface is in relief comprises a series of parallel needles pivoted on a common axis with their ends in engagement with the record, in such a manner that as the record passes under them the needles are oscillated in planes parallel to the direction of displacement of the record and produce vibrations of one or a number of diaphragms to which they are directly or indirectly connected. In the apparatus shown in Fig. 6, a sound record is used in which the sound-trace is formed as the line of separation between the base portion 1 of a film and a raised surface 2 thereon. A set of needles 4 is pivoted on a transverse support 5 and they are connected to upwardly-extending rods 6. These engage in a longitudinal groove 17 in a rod 7, which is held at one end by a ball-andsocket joint 8 and is connected at the other end to a sound-reproducing diaphragm 10. Vibrations of the needles 4, corresponding to the recorded sound, are caused as the film passes beneath them, and are transmitted to the diaphragm 10 through the rod 7. Instead of making that portion of the record which is in relief of uniform thickness, the thickness may increase transversely. Such a film record is used with the apparatus shown in Fig. 7. In this construction, the sound-reproducing diaphragm consists of a number of strips 10, stretched in juxtaposition across the base of a resonating chamber 13. The strips are respectively connected to the ends of a number of needles 4 the points of which engage with the record 1, and which are pivoted on an inclined rod 5. A record having a surface in constant relief may be used with a modified form of this apparatus, where;n levers of varying lengths are provided between the needles 4 and the strips 10, to amplify the movements of the needles according to their position with respect to the effective edge of the relief surface 2.

Filed: 1934-12-07
Abstract: 448,859. Centreless grinding. B.S.A. TOOLS, Ltd., Armoury Road, Small Heath, and OGILVIE, W., c/o B.S.A. Tools, Ltd., Montgomery Street, Sparkbrook, both in Birmingham. Dec. 7, 1934, No. 35134. [Class 60] In a centreless grinder of the type having peripherally opposed grinding and control wheels and adapted for through or infeed grinding, one of the wheels is adjustable relatively to the other by a feed screw 2, which may be operated by a hand wheel 6 for initial adjustments or by a lever carried by a clutch box 8 adapted to be locked to the screw by a bolt 9. In order that a slow feed and a rapid feed may be given to the movable wheel, as for example, when grinding shouldered work, the screw carries rotatably a sleeve 11 confined between a shoulder 12 and a thrust bearing 13, and on the sleeve 11 is slidably but non- rotatably mounted a sleeve 14 having a flange 19 rotatably located in a recess 20 in a plate 21 secured to the machine frame 22. The sleeve 14 has therein a cam groove with a circumferential part 16 and a helical part 15, the groove being engaged by a roller 17 carried by the box 8, and the sleeve may be locked against rotation by a plug 23 carried by the plate 21 and adapted to be engaged in a hole 24 in the sleeve, or by further movement to engage a pad 25 to lock the screw 2 against rotation when through grinding is in operation. The remote end of the screw 2 carries a sleeve 27 slidably keyed in a bracket 30 secured to the machine frame 22<a>, a plug 33 serving to lock the sleeve and the screw against longitudinal movement by entering a hole 35 in the sleeve. In operation, the sleeve 14 is locked by the plug 23 and rotation of the screw by the handle on the clutch box 8 causes the roller 17 to run along the helical slot 15 thus moving the screw axially and at the same time rotating it. When the roller runs in the slot 16, the screw rotates only, thus giving a slow feed to the wheel. In a modification, the sleeve 27 and associated parts are omitted, and in order to prevent axial movement of the screw, the plug 23 is adapted to enter a hole in the sleeve 11 ; the cam sleeve 14 is fixed and the roller engaging the cam is releasably secured to the clutch sleeve 8.

Filed: 1934-12-07
Abstract: 442,103. Cathode-ray tubes. NICOLL, F. H., 17, The Drive, Ickenham, and BROADWAY, L. F., Strathmore, Park Way, Hilling- don, both in Middlesex. Dec. 7, 1934, No. 35295. [Class 39 (i)] In cathode-ray tubes having within an evacuated envelope an electron lens formed by two tubular, coaxial electrodes with their ends spaced apart and also having near the lens a conductor subject to varying potentials, the field of the lens is screened from the conductor by a shield around the gap between the two electrodes and between this gap and the conductor, and this shield overlaps one electrode and either overlaps the other electrode or is united thereto by an annular screen. A tube having a cathode shield 6, accelerator 7, modulating electrode 8, first anode 9 and second anode 10 connected at 13 to a wall coating 12 has the lens field between the electrodes 9, 10 screened from the leads 21, 22 to the deflecting plates 14, 15 by an enlarged extension 23 and flange 23<a> on the electrode 10. The electrodes 6.. 10 are all tubes of the same diameter with diaphragms as shown. The diaphragm 101 with a small aperture 10<a> screens the field between the electrodes 9, 10 from the deflecting plates and is at the end of the electrode 10 remote from the electrode 9 and at a distance from the gap between the electrodes 9, 10 at least equal to the diameter of these electrodes. In modifications, the extension 23 is on the electrode 9 or is replaced by an annular screen of wire mesh or continuous metal overlapping both electrodes and electrically connected to either or to any steady potential inside or outside the tube or left unconnected. The invention may also be applied to screening the field between the electrodes 6, 7 from the conductors 21, 22 and to screening the field between two electrodes from the metal supporting rods which are described in Specification 437,594 and which are subject to potential variations as by induction.
